VERY flimsy glassware, extremely delicate, was on its 3rd glass, when I tossed it, and bought an HerbalAire ... also, it's temperature depends as much on strength of your 'intake', as the element itself (a Radio Shack replacement soldering pencil element) ... a little too 'basic' for my tastes ... overall, too much like a 'toy' to keep me using it ... buy one, use one, compare them, it's no contest, just my opinion ... regardless, enjoy
